Data movement bottlenecks are the single greatest limiting factor in developing novel hardware for machine learning. We use silicon photonics to break through these barriers, and we're re-architecting the entire AI hardware stack in order to provide multiple-order-of-magnitude improvements in bandwidth and performance. We are creating a hardware/software solution that will outperform the world's largest AI supercomputers.Luminous is backed by Bill Gates, Luke Nosek, Ali Partovi and Dara Khosrowshahi, among others.
